<h3>User Interface</h3>
<p>
    The OWT Classification processor can be invoked from the SNAP tool menu by selecting
    the <b>OWT Classification</b> command from the <b>Processing / Thematic Water Processing</b> menu. On the
    command line the OWT Classification processor is
    available by means of the Graph Processing Tool <code>gpt</code> which is located in the SNAP <code>bin</code>
    directory. Typing <code>gpt OWTClassification -h</code> displays further information.
</p>


<h4>I/O Parameters Panel</h4>
<p align="center"><img src="images/OwtIOParameter.png" alt="I/O Parameters of OWT Processor"></p>

<h5>Source Product Group</h5>

<p class="i1">
    <b>Source product:</b>
    Specify the source product. Any atmospherically corrected water spectra should work if it contains the wavelength necessary for the selected OWT-Type.
    The combo box presents a list of all products opened in SNAP.
    The user may select one of these or, by clicking on the button next to the combo box, choose a product
    from the file system.
</p>

<h5>Target Product Group</h5>

<p class="i1">
    <b>Name:</b>
    Used to specify the name of the target product.
</p>

<p class="i1">
    <b>Save as:</b>
    Used to specify whether the target product should be saved to the file system. The
    combo box presents a list of available file formats.
    The text field or the button next to it allow to specify a target directory.
</p>

<p class="i1">
    <b>Open in SNAP:</b>
    Used to specify whether the target product should be opened in SNAP.
    When the target product is not saved, it is opened in SNAP automatically.
</p>

<h4>Processing Parameters Panel</h4>
<p align="center"><img src="images/OwtProcParameter.png" alt="Processing Parameters of OWT Processor"></p>

<p class="i1">
    <b>OWT Type:</b> Select one of the available types from the predefined list.
    For a description of the types see the <a href="OwtAlgorithmSpecification.html">Algorithm Specification</a>
    The OWT type defines which wavelengths are needed. The the maximum distance to the requested wavelength is 10 nm.
</p>

<p class="i1">
    <b>Reflectances prefix:</b>
    Specifies the prefix of the reflectance bands which are used for processing. Only bands starting with this prefix will be considered as spectrum provider.
</p>

<p class="i1">
    <b>Input reflectance is:</b>
    Specifies if the input reflectance is either radiance reflectances or irradiance reflectances (ESA compatible).
    For OLCI or MERIS chose IRRADIANCE_REFLECTANCES for MODIS use RADIANCE_REFLECTANCES.
</p>

<p class="i1">
    <b>Write input reflectances:</b>
    Whether or not the input reflectances shall be copied into target product.
